SHAFT-OPERATING MECHANISM.

ori inal application filed A rn so; 1920, Serial No. 377,811. mviae'aand. this application filed March To all whom it may concern:

Be it known that I, ADOLPH KAssLER, residing at New York, in the countyand State of New York, and being a citizen of the United States, haveinvented certain new and useful Improvements in a Shaft-OperatingMechanism, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and to use the same, reference being had to theaccompanying drawings, which illustrate the preferred form of theinvention, though it is to be understood that the invention is notlimited to the exact details of construction shown and described, as itis obvious that various modifications thereof within the scope of theclaims will occur to persons skilled in the art.

In said drawings:

Figure 1 is a section, taken on the line 1-1 of Figs. 4 and 7 of myimproved shaft operating mechanism showing it in one of its engagingpositions;

Figure 2 is a section taken on line 2-2 of Fig. 5 showing the device inits free or disengaged position;

Figure 3 is a section taken on line 33 of Fig. 6 showing the device inits other engaging position;

Figure 4: is a section taken on the line 44 of Fig. 1;

Fi ure 5 is a section taken on the line 5-5 of Flg. 2;

Fi re 6 is a section taken on the line 66 of Flg. 3;

Figure 7 is a section taken on, the line 77 of Fig. 1; and

Figure 8 is a section taken on the line 8-8 of Fig. 7, part of the shaftbeing broken away to show the shaft engaging I lug on the wheel hub.

It is the object of my invention to provide an improved shaft operatingmeans adapted to furnish a positive drive for the shaft in eitherdirection and to disengage the operating means from the shaft and permitthe shaft to rotate freely when the shaft rotates faster than theoperating means in one direction.

In the embodiment of my invention shown in the drawings, 1 designates ashaft adapted to rotate in suitable bearings or supports 2. Mounted onthe shaft 1 is a shaft operat- Serial No. 456,379.

mg means or wheel 3 having a hub 4 provided with an opening forming achamber 5 adapted to receive the shaft 1. The chamber 5 is of generalcylindrical shape and of suflicient diameter to receive the pin 6 fixed1n the shaft 1. The inner end of the hub 4 1S slotted, as at 7 in Fig.6, to permit the passage of the pin 6 and the outer end of the hub isbored to permit the end of the shaft to pass therethrough. After thewheel 3 is mounted on the shaft a pin 8 is passed through the shaft andits ends headed to prevent the withdrawal of the wheel from the shaft.Similar pins 9 serve to keep the shaft 1 in position in its bearings 2.

At the ends of the chamber 5 are inwardly extending projectings orshoulders 10 and 1 1, the projections 10 having their outer facesperpendicular to the hub axis while the projections 11 are each providedwith an inclined face 12 extending from the base of the projection tothe outer edge of the front or engaging face of the projection orshoulder. The projections 10 andll are adapted to be engaged with thepin 6 and thus provide a means for rotating the shaft 1 in eitherdirection by the wheel 3.

To operate the shaft 1, the wheel 3 ma be moved inwardly manually on thesha 1 so as to bring the projections 10 into en- 1 gagement with the pin6 to rotate the shaft 1 in a counter-clockwise direction, as shown inFig. 7., or the wheel 3 may be moved outwardly manually on the shaft 1to engage the projections '11 with the pin 6 to rotate the shaft 1 in aclockwise direction, as shown in Fig. 4. When the projections 11 are inengagement with the pin 6 any increase in the speed of the shaft 1 orany reversal ofthe direction of rotation of the wheel 3 will cause thepin'6 to engage with the inclined faces 12 of the projections 11 and toautomatically shift the wheel 3 along the shaft 1 to a position in whichthe pin 6 will not engage either the projections 11 or the projections10 so that the shaft may revolve freely relatively to the wheel 3 andthe wheel 3 may have its direction of rotation changed without stoppingthe rotation of the shaft 1.

j This application is a division of my copending application, Serial No.377 ,811, filed April 30, 1920, which resulted in Patout No. 1,415,097,issued May 9, 1922,

What I claim is:

1. A shaft, shaft 0 eratin means mounted on said shaft having a cambered hub and en aging means in said hub chamber adapte to rotate saidshaft in either direction, said engaging means being adapted to shiftsaid operating means on said shaft to a position in which said operatingmeans rotates freely on said shaft in either direction.

2. A shaft, shaft operating means having a chambered hub movablelongitudinally of said shaft and having shaft engaging means formed insaid hub chamber, said shaft engaging means being adapted, in oneposition, to rotate said shaft in one dlrection, in another position torotate said shaft in the other direction and to permit free rotation ofsaid shaft in either direction in a third position, said shaft beingadapted to engage said shaft engaging means to move said operating meansto the third position from one of the other positions.

3. A shaft, shaft operating means having a chambered hub mounted on saidshaft, shaft engaging means formed in said hub chamber and adapted torotate said shaft in either direction and means on said shaft adapted toengage said shaft engaging means to shift said operating means alongsaid shaft to a position in which said shaft may rotate freely in saidoperating means.

4. A shaft, operating means for said shaft having a chambered hub andengaging means on said shaft and in said hub chamber adapted .to engageto rotate said shaft in one direction and to engage to shift saidoperating means along said shaft to a position in which said shaft mayrotate freely in either direction with respect to said operating means..4

5. A shaft, operating means movable on said shaft and having a chamberedhub and engaging means on said shaft and in said hu chamber adapted, inone position of said operatlng means, to engage to rotate said shaft inone dlrection, in a second position, to engage to rotate said shaft inthe opposite direction and to engage in one of said positions to shiftsaid operating means along said shaft to a position in which said shaftmay rotate freely in said operating means.

6. A shaft having engaging means thereon, operating means for said shafthaving a chambered hub and movable longitudinally of said shaft, meansin said hub chamber adapted to engage the means on said shaft to rotatethe shaft in one direction, said means being adapted to engage to shiftsaid operating means along said shaft to a position in which said shaftmay rotate freely in either direction-in said huh.

7. A shaft having engaging means there on, operating means for saidshaft having a chamberedhub and movable longitudinally of said shaft andmeans in said hub chamber adapted to engage the engaging means on saidshaft to rotate said shaft in either direction, said means being adaptedin one position of said operating means, to be engaged by said engagingmeans to shift said operating means to a position in which said shaftmay rotate freely in said hub.

8. A shaft having engaging means thereon, operating means for said shafthaving a chambered hub and movable longitudinally of said shaft,projections in said hub chamber adapted to engage said engaging means inone position of said operating means to rotate said shaft in onedirection and to engage said engaging means in another position torotate said shaft in the other direction, said projections beingadapted, in one of said positions, to be engaged by said engaging meansto shift said operating means to a osition in which said shaft mayrotate free y in said hub.

In Witness whereof I have hereunto set my hand in the presence of twowitnesses.
